DETROIT TRANSIT HISTORY.info: DDOT #1000-1100 Series Buses

D-DOT'S FIRST FLEET OF NEW BUSES
(New D-DOT Coaches for One Dollar!)

In June of 1974, the Southeastern Michigan Transportation Authority (SEMTA) – the regional transit authority
responsible for obtaining federal grant monies for local transit projects – was awarded $9.1 million in federal and state
grant money toward the purchase 148 new buses for the City of Detroit's DSR bus system. However, the city-owned
DSR days would soon be numbered, as the Detroit Department of Street Railways (DSR) operation was slated to
undergo a restructuring the following month, becoming the Detroit Department of Transportation (D-DOT).

In January, 1975, an additional $12.5 million federal grand was also obtained by SEMTA for an additional 99 coaches
and other new equipment, which would increase the total number of new buses for the region to 247 coaches. Nearly
80% of the total funding would go towards new buses slated for Detroit, while the remainder of funds would go toward
purchasing new buses for SEMTA's suburban bus operation. The additional grant would also allow SEMTA to purchase
an additional fifty plus coaches for DDOT. The local share money was obtained through a special half-cent state gasoline
and weight tax diverted to mass transit.

Two orders totaling 196 new buses were placed with General Motors Truck & Coach in Pontiac, Mich., with 148 of
the coaches being slated for DDOT, and 48 being earmarked for SEMTA. An order for an additional 51 new buses for
DDOT would later go to AM General. The arrival of the GMC coaches would be the first new buses for the region since
the 154 fleet of GMC T8H-5307A's — which were also purchased through SEMTA — were delivered in 1972.

Beginning in June of 1975, the first of the DDOT fleet of 148 new
"air-conditioned" GMC coaches (#1001-1148) began arriving.
These would be the first new fleet of buses received under DDOT,
and the last GMC "new-look" style coaches to be purchased for
the city. The new buses, costing $62,000 each, were purchased
through SEMTA with federal and state money, but would only
cost the City of Detroit one buck each. Actually, the buses would
be leased to the city for $1.00 per year per bus.

On Tuesday, June 10, 1975, Mayor Coleman A. Young showed
off the city's brand-new dollar-apiece buses to the media. The
Detroit Free Press quoted the mayor as saying, "Too many
of our buses are damn near collapse," and he explained that
the new buses would upgrade the city's bus service.

The coach's improved parking brake system also allowed the operator to more securely park the vehicle. The older style
"Johnson Bar" mechanical parking brake — which was applied by manually pulling up on a long lever — had now been

Interestingly, the new paint scheme used on these new coaches began to find its way over to the older coaches in the
fleet, as the department began to repaint a number of its older GMC "new-looks" with the new DDOT livery. However,
this original DDOT color scheme was short-lived. Shortly after the arrival of the GMC RTS-II coaches in 1978, DDOT
began repainting a number of older coaches in the fleet, patterning them after the RTS paint scheme design. When a
number of the T6H-5307A's were rehabbed by the Blitz Body Corporation of Chicago during the mid-1980's, they
too were repainted reflecting the RTS paint scheme design. But after the arrival of the new #2000-series MCI Classics
in 1989, which introduced a revised DDOT green and yellow double cross-over stripe design, the department began to
repaint its fleet again. The few remaining #1000-1100-series new-looks still in service during the early 1990's were also
repainted into the newly designed DDOT color scheme.

The last of the remaining #1000-1100-series T6H-5307A's were all retired by the mid-1990's.

This photo shows the interior of SEMTA coach #1547.
Although the 48 SEMTA coaches came with blue
forward facing seats and no center exit doors, the
original brown and tan interior color scheme was
identical to the T6H-5307A's delivered to DDOT.

The interiors of the DDOT fleet took on a different
appearance after being rehabbed by the Blitz Corp
during the mid-1980's. The interior color scheme
was changed to black and off-white, and the
multi-colored seats were replaced by black seats.

These two photos, taken at the Coolidge Terminal graveyard, shows the second paint scheme used on the
T6H-5307A fleet. After the arrival of the GMC RTS-II's in 1978, a number of the #1000 and #1100-series
coaches were repainted similar to the design introduced on the RTS coaches. When the T6H-5307A fleet
was rehabbed in 1985, they were repainted using the RTS stripe design paint scheme.

After the arrival of the #2000-series MCI Classics in 1989, DDOT introduced its third and current paint
scheme design. The last of the remaining T6H-5307A's still in operation during the early 1990's were also
repainted with this revised stripe design. These two photos show two of the last #1100-series coaches
sporting this third DDOT color scheme while waiting to enter that bus graveyard in the sky.

This June 11, 1975 Detroit Free Press photo shows a
smiling Mayor Coleman A. Young along-side one of the
city's new $1-a-year D-DOT buses.

The air-operated parking brake
was activated by a control
valve knob located on a tower
to the right of the driver's seat.

replaced by an air-operated "DD3" parking and emergency brake system. This new type of
parking brake had to be activated by pulling up on a control valve knob located on a tower
placed on the floor to the right of the driver's seat. To release the parking brake the operator
had to push down on the control valve knob and then make a full service brake application,
by pushing the brake pedal all the way down to the pedal stop before the coach could be
moved. An emergency "safety" feature in the system would automatically engage the rear
brakes and bring the coach to an abrupt stop if the air pressure was to drop below 40 PSI.
Under the manual parking brake system the vehicle would be much more difficult to bring to
a stop in the event of sudden air pressure loss. Obviously, these new coaches were definitely
far more advanced compared to their predecessors.

The new GMC coaches, model T6H-5307A, arrived sporting the new DDOT color scheme of white with black trimmed
windows and green and yellow striping. These coaches would initiate the fleet numbering sequence still being followed by
DDOT coaches today, and were the first to display the current route name and route number assignment most DDOT
routes still follow. The T6H-5307A's were also the first Detroit buses purchased since the 1940's that could display the
coach's route name on the side of the coach. A separate "hand-cranked" roll-sign box, located above the first right-side
passenger window, would display that information. (A motorized sign box would later be installed on rehabbed coaches)

In addition to being the first new buses to arrive in Detroit equipped with power-steering, these 48-passenger coaches
came equipped with a number of other features new to the city. The new features included: a computerized wheel lock
control braking system to prevent skidding, foot-operated directional signal switches, plush cushioned brightly-colored
seats, and a much improved interior lighting.

These two interior photos of DDOT coach #1131 show the original interior colors found on the new fleet of GMC T6H-5307A's.
Their plush brightly-colored cushioned seats are clearly visible in both photos (click-on each photo to view larger image).
Unfortunately, the cushioned seating became targets of vandalism, and were replaced with more conventional black color
seats when the coaches were rehabbed some years later. (Photos courtesy of the Schramm Collection)

ON A SIDE NOTE: As mentioned above, the Southeastern Michigan Transportation Authority also received a fleet
of T6H-5307A's. At the completion of the DDOT coach order, production continued at GMC Truck & Coach on 48
coaches (#1521-1568) slated for SEMTA. These would become the first new buses to be both owned and operated
by SEMTA. As one would expect, most of the advance new features found on the DDOT fleet were also included on
the SEMTA coaches. However, the SEMTA coaches had suburban style forward facing seats and came with no center
exit doors.

Since color photos of the DOOT #1001-1148 coach fleet seem hard to come by, I've decided to post this bus-
drawing showing the original paint scheme used on the GMC "T6H-5307A" fleet when delivered in 1975.

DDOT's original – but "short-lived"– livery of white with black trimmed windows and green and yellow striping
was introduced on the #1000–1100 series GMC "new-look" fleet that began arriving in June, 1975. Because the
buses were purchased through SEMTA, the SEMTA logo decal was displayed on the transmission door panel.
